A Sense Of Touch For Robotic Surgery ToolsBy substituting mechanical instruments for human fingers, robotic tools give surgeons a new way to perform medical procedures with great precision in small spaces. But as the surgeon directs these tools from a computer console, an important component is lost: the sense of touch.
Johns Hopkins scientists are trying to change that by adding such sensations, known as haptic feedback, to medical robotic systems. "Haptic" refers to the sense of........Go to the Research news blog (Added on 11/29/2006 5:09:01 AM)
The impact of immunosuppressive medicationsPatients with rheumatoid arthritis (RA) have an increased risk of heart attack and stroke. As per extensive evidence, the key driver for this increased risk of cardiovascular disease is the increased systemic inflammation characteristic of RA. Studies are less clear on whether medications that work to reduce RA's inflammatory symptoms provide protective benefits against cardiovascular events. Some data have suggested that the most potential........Go to the Rheumatology news blog (Added on 11/29/2006 4:34:08 AM)
